Description

Technical Field

[0001] The invention relates to the technical field of surgical instruments, in particular to a depth-adjustable bone drill for animal experimental surgery. Background Art

[0002] Currently, when conducting experiments on animals, it is often necessary to drill holes in the bones of the animals. The tool used is usually a bone drill, which can greatly improve the efficiency of the operation.

[0003] After searching, the invention with Chinese patent publication number CN220558063U discloses a fixed-depth bone drill device, wherein the fixed-depth bone drill device includes: a support seat, which is provided with an assembly channel running through the support seat; a rotating shaft, one end of which is rotatably arranged inside the assembly channel, and the other end of which extends to the outside of the assembly channel; a bone drill member, one end of which is arranged inside the assembly channel and connected to one end of the rotating shaft, and the other end of the bone drill member extends to the outside of the assembly channel in a direction away from the rotating shaft.

[0004] When the above device is in use, the bone debris broken by the drill will be transferred to the outside of the bone. Since the bone debris is relatively small and has a certain viscosity in the animal body, it will become difficult to clean it, thereby greatly increasing the operation time. There is room for improvement. Summary of the invention

[0005] The purpose of the present invention is to provide an adjustable depth bone drill for animal experimental surgery to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an adjustable depth bone drill for animal experimental surgery, comprising a bone drill body, a drill bit clamped inside the rotating end of the bone drill body, a cleaning assembly installed outside the bone drill body, the cleaning assembly surrounds the outside of the drill bit, the cleaning assembly comprises two extension plates fixedly connected to the outside of the bone drill body, the two extension plates are distributed horizontally, a connecting rod is slidably inserted inside the two extension plates, one end of the bottom of the two connecting rods is fixedly connected to the same focusing cover, the focusing cover surrounds the outside of the drill bit, and one or more connecting pipes are fixedly inserted at the top of the focusing cover.

[0007] As a further preferred embodiment of the adjustable depth bone drill for animal experimental surgery of the present invention, one or more suction pipes are fixedly connected to the outer wall of the bottom of the centralizing hood, and the one or more suction pipes are all connected to the centralizing hood, and the air inlet ends of the one or more suction pipes are connected to each other.

[0008] The bone debris conducted from the spiral groove can be cleaned and collected in time, without the need for cleaning after surgery, and can also prevent bone debris from falling into the tissue to increase the difficulty of cleaning. The external suction equipment is started, and the air inside the connecting pipe, the central hood and multiple suction pipes is evacuated to generate negative pressure. The multiple suction pipes will generate suction, and the bone debris conducted up will be absorbed at the first time. Because the drill bit is in a continuous rotating state, the bone debris conducted up will be distributed in a ring shape, and the multiple suction pipes are also distributed in a ring shape, which can ensure that these bone debris can be cleaned. The central hood can be moved up and down with the cooperation of two connecting rods and two extension plates, thereby ensuring that it will not move with the movement of the bone drill body, so that the bone debris can be absorbed sufficiently in a timely manner.

[0009] As a further preferred embodiment of the adjustable depth bone drill for animal experimental surgery of the present invention, an adjustment component is installed on the outside of the bone drill body, and the adjustment component includes a support frame fixedly connected to the outer wall of one side of the bone drill body, the support frame is vertically arranged, and two vertically arranged limit rods are fixedly connected inside the support frame, and the two limit rods are externally slidingly sleeved with the same movable plate, and the movable plate is located at the top position of the two connecting rods.

[0010] As a further preferred embodiment of the adjustable depth bone drill for animal experimental surgery of the present invention, a vertically arranged screw rod 1 is rotatably connected to the inside of the support frame through a bearing, the screw rod 1 forms a transmission fit with the movable plate, and a knob is coaxially fixed to one end of the top of the screw rod 1.

[0011] As the hole gradually deepens, the movable plate will move downward synchronously with the bone drill body, and then the movable plate will contact the top of the connecting rod. Since the length of the connecting rod is fixed, the bone drill body will be unable to move further. If you need to adjust the drilling depth, just drive the screw rod to rotate through the knob. The movable plate restricted by the two limit rods can only move in the vertical direction. Therefore, when the screw rod rotates, the movable plate can be driven to move, and then the movable distance of the bone drill body will also change accordingly, which is beneficial to improve the adaptability of the device.

[0012] As a further preferred embodiment of the depth-adjustable bone drill for animal experimental surgery of the present invention, a vertically arranged scale line is provided on the outer wall of one end of the bone drill body, and the scale line is parallel to the limit rod.

[0013] As a further preferred embodiment of the depth-adjustable bone drill for animal experimental surgery of the present invention, a weighted ball is disposed at one end of the top of each of the two connecting rods.

[0014] As a further preferred embodiment of the depth-adjustable bone drill for animal experimental surgery of the present invention, a sterile cover is provided outside the central cover, and a rubber band is provided at the top of the sterile cover.

[0015] The present invention provides an adjustable depth bone drill for animal experimental surgery, which has the following beneficial effects: (1) The present invention can clean and collect the bone debris conducted by the spiral groove in time by providing a cleaning component. There is no need to clean it after surgery, and the bone debris can be prevented from falling into the tissue to increase the difficulty of cleaning. The external suction device is started, and the air inside the connecting pipe, the central cover and the multiple suction pipes is evacuated to generate negative pressure. The multiple suction pipes will generate suction, and the bone debris conducted up will be sucked up immediately. Because the drill bit is in a continuous rotating state, the bone debris conducted up will be distributed in a ring shape, and the multiple suction pipes are also distributed in a ring shape, which can ensure that the bone debris can be cleaned up. The central cover can be moved up and down by cooperating with the two connecting rods and the two extension plates, so as to ensure that it will not move with the movement of the bone drill body, so that the bone debris can be sucked up in a timely manner.

[0016] (2) The present invention provides an adjustment component. As the hole gradually deepens, the movable plate will move downward synchronously with the bone drill body. Then the movable plate will contact the top of the connecting rod. Since the length of the connecting rod is fixed, the bone drill body will be unable to move further. If the drilling depth needs to be adjusted, the screw rod can be rotated by the knob. The movable plate restricted by the two limit rods can only move in the vertical direction. Therefore, the movable plate can be driven to move when the screw rod rotates, and the movable distance of the bone drill body will also change accordingly, which is conducive to improving the adaptability of the device.

DETAILED DESCRIPTION

[0019] The technical solution of the present invention is further described in detail below in conjunction with the accompanying drawings: The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. The present invention is described in detail below based on the drawings and preferred embodiments, and the purpose and effect of the present invention will become clearer. It should be understood that the specific embodiments described here are only used to explain the present invention and are not used to limit the present invention.

[0020] The present invention provides a technical solution: Figure 1 , Figure 2 and Figure 3 As shown, in this embodiment, an adjustable depth bone drill for animal experiment surgery includes a bone drill body 1, a drill bit is clamped inside the rotating end of the bone drill body 1, a cleaning assembly 3 is installed outside the bone drill body 1, the cleaning assembly 3 surrounds the outside of the drill bit, and the cleaning assembly 3 includes two extension plates 301 fixedly connected to the outside of the bone drill body 1, the two extension plates 301 are horizontally distributed, and a connecting rod 302 is slidably inserted inside the two extension plates 301, and one end of the bottom of the two connecting rods 302 is fixedly connected to the same centralizing cover 303, the centralizing cover 303 surrounds the outside of the drill bit, and one or more connecting tubes 305 are fixedly inserted on the top of the centralizing cover 303.

[0021] One or more air intake pipes 304 are fixedly connected to the outer wall of the bottom of the centralizing cover 303 , and the one or more air intake pipes 304 are all connected to the centralizing cover 303 , and the air inlet ends of the one or more air intake pipes 304 are connected to each other.

[0022] The external suction device is started, and the air inside the connecting pipe 305, the central cover 303 and the multiple suction pipes 304 is evacuated to generate negative pressure. The multiple suction pipes 304 will generate suction, and the bone residues transmitted up will be sucked up immediately. Since the drill bit is in a continuous rotating state, the bone residues transmitted up will be distributed in a ring shape, and the multiple suction pipes 304 are also distributed in a ring shape, which can ensure that the bone residues can be cleaned up. The central cover 303 can move up and down with the cooperation of the two connecting rods 302 and the two extension plates 301, thereby ensuring that it will not move with the movement of the bone drill body 1, so that the bone residues can be sucked up sufficiently in a timely manner.

[0023] like Figure 1 and Figure 4 As shown, an adjustment component 4 is installed on the outside of the bone drill body 1, and the adjustment component 4 includes a support frame 401 fixedly connected to the outer wall of one side of the bone drill body 1, and the support frame 401 is vertically arranged. Two vertically arranged limit rods 404 are fixedly connected inside the support frame 401, and the two limit rods 404 are externally slidably sleeved with the same moving plate 403, and the moving plate 403 is located at the top position of the two connecting rods 302.

[0024] A vertically arranged screw rod 402 is rotatably connected inside the support frame 401 through a bearing, and the screw rod 402 forms a transmission fit with the movable plate 403, and a knob is coaxially fixed at one end of the top of the screw rod 402.

[0025] As the hole gradually deepens, the movable plate 403 will also move downward synchronously with the bone drill body 1, and then the movable plate 403 will contact the top of the connecting rod 302. Since the length of the connecting rod 302 is fixed, the bone drill body 1 will be unable to move further. If you need to adjust the drilling depth, just drive the screw rod 402 to rotate through the knob. The movable plate 403 restricted by the two limit rods 404 can only move in the vertical direction. Therefore, when the screw rod 402 rotates, the movable plate 403 can be driven to move, and then the movable distance of the bone drill body 1 will also change accordingly.

[0026] like Figure 1 As shown, a vertical scale line 2 is provided on the outer wall of one end of the bone drill body 1, and the scale line 2 is parallel to the limit rod 404. By referring to the scale line 2, the adjustment process can be ensured to be more accurate.

[0027] like Figure 1 As shown, a weighted ball 306 is disposed at one end of the top of the two connecting rods 302, which can ensure that the suction tube 304 is always attached to the top of the bone under the action of gravity.

[0028] like Figure 3As shown, a sterile cover 5 is provided on the outside of the centralizing cover 303 , and a rubber band is provided on the top of the sterile cover 5 to prevent the bone drill body 1 from directly contacting the patient's tissue, and the rubber band can limit the sterile cover 5 .

[0029] The present invention can clean and collect the bone residues conducted by the spiral groove in time by arranging a cleaning component, and there is no need to clean it after the operation, and the bone residues can be prevented from falling into the tissue to increase the difficulty of cleaning. The external suction device is started, and the air inside the connecting pipe, the central cover and the multiple suction pipes is evacuated to generate negative pressure. The multiple suction pipes will generate suction, and the bone residues conducted up will be sucked up at the first time. Because the drill bit is in a continuous rotating state, the bone residues conducted up will be distributed in a ring shape, and the multiple suction pipes are also distributed in a ring shape, which can ensure that the bone residues can be cleaned up. The central cover can be moved up and down under the cooperation of the two connecting rods and the two extension plates, so as to ensure that it will not move with the movement of the bone drill body, so that the bone residues can be sucked up sufficiently in time.

[0030] The present invention provides an adjustment component. As the hole gradually deepens, the movable plate will move downward synchronously with the bone drill body, and then the movable plate will contact the top of the connecting rod. Since the length of the connecting rod is fixed, the bone drill body cannot move further. If the drilling depth needs to be adjusted, the screw rod can be rotated by the knob. The movable plate restricted by the two limit rods can only move in the vertical direction. Therefore, the movable plate can be driven to move when the screw rod rotates, and then the movable distance of the bone drill body will also change accordingly, which is beneficial to improving the adaptability of the device.

[0031] The present invention provides an adjustable depth bone drill for animal experimental surgery, and the specific working principle is as follows: When the device is working, one end of the connecting tube 305 is connected to the external suction device, and the doctor holds the bone drill body 1 to perform the drilling operation. After the bone is broken, it will be transmitted to the top of the bone by the spiral groove of the drill bit. At the same time, the external suction device is started, and the air inside the connecting tube 305, the central cover 303 and the multiple suction tubes 304 is evacuated to generate negative pressure. The multiple suction tubes 304 will generate suction, and the bone residues transmitted will be sucked up at the first time. Because the drill bit is in a continuous rotating state, the bone residues transmitted will be distributed in a ring shape, and the multiple suction tubes 304 are also distributed in a ring shape, which can ensure that the bone residues can be cleaned up. The central cover 303 cooperates with the two connecting rods 302 and the two extension plates 301 , which can ensure that the focusing cover 303 can move up and down, thereby ensuring that it will not move with the movement of the bone drill body 1, so that the bone residue can be extracted in a timely manner. As the hole gradually deepens, the movable plate 403 will also move downward synchronously with the bone drill body 1, and then the movable plate 403 will contact the top of the connecting rod 302. Since the length of the connecting rod 302 is fixed, the bone drill body 1 will not be able to move further. If the drilling depth needs to be adjusted, just drive the screw rod 402 to rotate through the knob, and the movable plate 403 restricted by the two limit rods 404 can only move in the vertical direction. Therefore, when the screw rod 402 rotates, the movable plate 403 can be driven to move, and then the movable distance of the bone drill body 1 will also change accordingly.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
